This session aims to replicate the demands of a mountain bike ride / event, by constantly changing the intensity at which we ride at! Not only does the power demand change, but so does your cadence.
Half of the 'ramp up's' are to be completed at a low cadence of 65rpm, whilst the other half are at your chosen cadence. Meanwhile, the 'ramp down's' are to be completed at a more familiar cadence of 85rpm.
The efforts we complete today are typical of a tough mountain bike ride / race, where you could be riding through any sort of terrain that has varying terrain!
